Reviewed - Power Meter Pedals
These are arguably the easiest to fit power meters. Simply remove your existing pedals and fit these power metering pedals. Pedal based power meters are available as a single sided option with just ONE pedal fitted with the sensors, cheapest option. This type gives averaged total power by multiplying the power measured in one leg x 2.
They are also available as two pedal variants. Both pedals are fitted with the sensors giving TRUE left & right power measurement. These bi-lateral power meters provide the highest level of pedal power data including power phase and left / right balance. Expect to pay almost double the price of the single version.
